Remove hidden input when multi select is empty

[VictorChen]

When using a multi select with joinValues, the hidden input never gets removed.

eg:

<Select
  name="field-name"
  value={value}
  options={options}
  multi
  simpleValue
  delimiter="|"
  joinValues
/>

When the select is empty/cleared, the input still exists (with empty string as value):

<input type="hidden" name="field-name" value="">

It's pretty inconsistent right now where the single value Select will not include the hidden input if empty, but the multi value Select does? I feel like this should be addressed.
